Stephanie March says she had nothing to do with the "cheater" banner that flew above estranged husband Bobby Flay's Hollywood Walk of Fame ceremony.

Many assumed the 40-year-old actress commissioned the stunt, but March's attorney, Deborah Lans, told E! News, "Stephanie is absolutely not behind [this]."

Flay was receiving his star on the iconic sidewalk stretch Tuesday when fans noticed a green prop plane flying a "cheater" banner overhead. While it is unknown if the message was meant for the 50-year-old celebrity chef, Flay is rumored to have been unfaithful to March.

The estranged couple separated after 10 years of marriage in March.

The chef is accused of cheating on March with fellow Food Network star Giada De Laurentiis and former assistant Elyse Tirrell, but both Flay and De Laurentiis have denied the allegations.
